Section Properties For Cellular Decks Subjected To Negative Bending, Gregory L. Snow, W. Samuel Easterling
CCFSS Library (1939 - present)
Cellular decks are formed by attaching cold-formed “hat-shaped” deck sections on top of cold-formed steel sheets. The attachment is typically made using resistance spot welds spaced at a specific interval. The void left underneath the deck flutes and above the steel sheet provides a convenient means for the distribution of wiring and data cables throughout building systems. The section properties of cellular decks subjected to positive bending can be determined using the provisions of Chapter B of the 2001 AISI Specification (AISI, 2001). However, the provisions of Chapter B do not apply to cellular decks subjected to negative bending unless …

American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)
The Standard for Cold-Formed Steel Framing - Prescriptive Method for One and Two Family Dwellings, AISI S230-07, as well as other industry span and load tables are based on the standard web openings (i.e., punchouts), as defined in the North American Standard for Cold- Formed Steel Framing - Product Data, AISI S201-07. Presented in this report are the findings from an extensive testing program conducted at McMaster University on full-scale floor joists having larger web openings. Presented is an initial Final Report (86 pages) that was issued by the researcher in March 2007, as well as the results of Additional …

Strength Of Cold-Formed Steel Jamb Stud-To-Track Connections, A. Victor Lewis, Reinhold M. Schuster, Steven R. Fox
American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)
The North American Standard for Cold-Formed Steel Framing - Wall Stud Design, AISI S211-07, provides a design expression for web crippling at the end reaction of the single stud-to-track connection. The subject of this report is an experimental investigation that was carried out at the University of Waterloo to establish a similar design expression for multiple jamb stud members. It is anticipated that the AISI Committee on Framing Standards will consider the results of this study in the development of future standards and the Cold-Formed Steel Engineers Institute in the development of design aids. The American Iron and Steel Institute …
Strength Of Arc-Spot Welds Made In Single And Multiple Steel Sheets, Gregory L. Snow, W. Samuel Easterling
Strength Of Arc-Spot Welds Made In Single And Multiple Steel Sheets, Gregory L. Snow, W. Samuel Easterling
CCFSS Library (1939 - present)
The objective of this research was to establish a relationship between arc spot weld shear strength and the arc time used to form the weld. Lap shear tests were performed on both 3/4 in. and 5/8 in. nominal diameter welds. Each weld was formed in one-, two-, or four-layers of sheet steel ranging from 22 gauge (0.028 in.) to 16 gauge (.057 in.). Three distinct time series were tested for each unique weld size, thickness of sheet steel and layer configuration. The first of these series were the full-time welds. The two remaining series, 2/3-time and 1/3-time welds, had arc …

A Fast Adaptive Wavelet Scheme In Rbf Collocation For Nearly Singular Potential Pdes, Nicolas Ali Libre, Arezoo Emdadi, Edward J. Kansa, Mohammad Shekarchi, Mohammad Rahimian
A Fast Adaptive Wavelet Scheme In Rbf Collocation For Nearly Singular Potential Pdes, Nicolas Ali Libre, Arezoo Emdadi, Edward J. Kansa, Mohammad Shekarchi, Mohammad Rahimian
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
We present a wavelet based adaptive scheme and investigate the efficiency of this scheme for solving nearly singular potential PDEs. Multiresolution wavelet analysis (MRWA) provides a firm mathematical foundation by projecting the solution of PDE onto a nested sequence of approximation spaces. The wavelet coefficients then were used as an estimation of the sensible regions for node adaptation. The proposed adaptation scheme requires negligible calculation time due to the existence of the fast DiscreteWavelet Transform (DWT). Certain aspects of the proposed adaptive scheme are discussed through numerical examples. It has been shown that the proposed adaptive scheme can detect the …

We present a new method based upon the paper of Volokh and Vilney (2000) that produces highly accurate and stable solutions to very ill-conditioned multiquadric (MQ) radial basis function (RBF) asymmetric collocation methods for partial differential equations (PDEs). We demonstrate that the modified Volokh-Vilney algorithm that we name the improved truncated singular value decomposition (IT-SVD) produces highly accurate and stable numerical solutions for large values of a constant MQ shape parameter, c, that exceeds the critical value of c based upon Gaussian elimination.

The numerical solution of partial differential equations (PDEs) with Neumann boundary conditions (BCs) resulted from strong form collocation scheme are typically much poorer in accuracy compared to those with pure Dirichlet BCs. In this paper, we show numerically that the reason of the reduced accuracy is that Neumann BC requires the approximation of the spatial derivatives at Neumann boundaries which are significantly less accurate than approximation of main function. Therefore, we utilize boundary treatment schemes that based upon increasing the accuracy of spatial derivatives at boundaries. Increased accuracy of the spatial derivative approximation can be achieved by h-refmement reducing the …
